Very bad

Sluchek seems to slowly sink back into her own body. She gazes up at you, skin slick with sweat, with a twinkle in her eye. You know the infection has her firmly in its grip, but it's still a thrill to feel her hand return to your cock. It's an even bigger thrill to hear her say, “I think I need another lesson. A harder one. I've been very bad … sir.”

She strokes your cock, breathing deeply. Her other hand rubs a breast through the undershirt, fingertips sliding over the erect nipple.

“They do say spare the rod and spoil the child,” you say. “Go pick up that table so we can continue your punishment.” You give her ass a health slap to drive the point home. “Now. I don't like to wait.”

She releases your cock and trots across the room, what remains of her uniform obscuring most of her figure. As Sluchek rights the table again, you ensure her ass is fully uncovered. You want to taste your prize but there will be time enough for that later. Instead you tease her netherlips for a minute or two with the length of you cock, the tip reaching the pucker of her asshole, before you begin the next phase of her “punishment,” her final descent.

You wordlessly fill her completely with your giant crimson meat and pull out nearly all the way before ramming into her pussy again, your cock taking the place of your tail earlier. This time there is no counting, though, no end before she inevitably takes on her luscious hellspawn form. You set to work building the pace, your demonic balls slapping her ass at the bottom of every stroke, faster and faster, your cock giving her greedy cunt all it can handle.

“Fuck, like that. Give me more, sir. I need more!”

You like this impromptu deference. It must be burnt into her from her former profession but it can work in the new one as well.

“And you will have it,” you say, slipping a clawed finger slick with your saliva into her ass as you continue driving your cock into her sodden pussy, your unholy fluids pooling on the desk with her juices. After ensuring she's ready for your tail, you start plundering her ass with your newest cock, reveling in the feel of her around your two cocks.

“Oh yeah, fill those dirty holes! Plug me with those magic fucking cocks! Fucking take my ass!”

“Such a dirty slut. Dirty sluts aren't good girls. Didn't I say bad girls go to hell? Do you want to go to hell?”

“Anywhere these cocks go,” she says, her hands gripping the table starting to scratch the surface with her growing nails. Her matted hair is streaked with black, and she somehow feels tighter around your cock, the heat in her pussy intense as the virus burns through her. “You fill me up so good, sir.”

“If you serve my mistress, you'll have all the cock and pussy you can devour,” you say. “I just need your delicious soul.”

A shudder goes through Sluchek. She looks back at you with slit eyes set in a reddening face. “Take it,” she husks. “Just give this slut your cum.”

Your roar triumphantly and flood the former cop with black cum, causing her to scream as her own orgasm rolls over her. After your climax, you pull out and admire the way Sluchek's torn uniform hugs her legs, only the tarry-covered apple ass and pussy bulging out seductively. The corrupted officer crawls off the table and kneels before you, sucking your cocks cleans alternately, her expanded tits stretching the shirt to its limit, having improbably survived the fuck session and her transformation.

“Arise, demon,” you say. “It's time to increase the ranks of Lilith and take full control of this station.”
